This is true. chan_ss7 may initiate an outgoing call on a CIC thiat is blocked 
for local maintenance.  chan_ss7 will not initiate calls on CICs that are 
hardware blocked or that are blocked for remote maintenance.

The next version of chan_ss7 will have an option for the CLI block and unblock 
commands that state whether chan_ss7 may initiate calls on CIC that are 
blocked for local maintenance. This will ease maintenance operations.
